SHEET-DELIVERY MECHANISM FOR :enmrrnc-rnnssns;

Application filed October 30,

To all whom it may concern Be it known that I, HOWARD M. BARBER,a

citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Sheet-Delivery Mechanism for Printing-Presses, of which the following is a specification.

The object of my invention is to provide novel means for insuring the rapid delivery means for operating one set of grippers every revolution of the carrier at both the taking and delivery points and for operating the other set of grippers every second revolution of the carrier at the taking and delivery points, whereby a collection of two sheets is obtained, thus giving the fly ample time to perform its functions even at a very rapid operation of the press.

In the accompanying drawings.

Figure 1 is a detail view partly in side el vation and partly in section of a'sheet feed-; ing carrier, the impression cylinder, delivery carrier and fly.

Fig. 2 is a detail View of the cams and gears at the far side of the press.

' Fig. 3 is a plan view of the delivery carrler.

Fig. 4 is a detail front vlew of the same on a larger scale. 7

Fig. 5 is a detail section on the same scale as Fig. 4 in the plane of the line VV of Fig. 3, and 1 Fig. 6 is a detail section on a similar scale in the plane-of the line VL-VI of Fig. 3.

'The sheet feeding'carrier in the present instance, a reel 1 has a set of grippers 2. The impression cylinder 3, is shown as having a plurality of impression surfaces 4 and sets of grippers 5 arranged to take successive sheets from the set of grippers 2. The combined sheet collecting and delivery carrier, in the present instance a reel 6, is shown as having two alined sets of grippers 7 and 8. The fly 9 is arranged to deliver the collected sheets from the delivery carrier 6 to a table 1918. Serial in. 260,361.

or other point not shown herein,i t being .derstood that any suitable 'means of Well ate the set of grippers '7 at'the taking and dellvery polnts every revolution of the do livery carrier and the set of grippers. 8 every second revolution at the taking anddelivery i points, is constructed, arranged and oper ated as follows:

Each gripper 7 is loosely mounted on the i rocking gripper shaft ,10 and it is held yieldlngly closed by means of a spring 11 coiled] around the gripper shaft one end of the spring pressing on the grippers and the other end anchored in a collar fixed to the i g shaft. The gripper 7 has a stud 12engaged by an arm 13 fixed to a rock shaft lfwhich rock shaft has an operating arm 15 provided with a stud or roller 16 in position to be engaged by the stationary cam 17 at the taking point and a stationary cam 18 at the delivery point. The grippers S are fixed to the gripper shaft .10 which shafthas the usual v operating arm 19 provided with a'stud or 1 roller 20 arranged to be engaged by a movable -ca1n2-1. This cam isprovided with an 'operatlng arm 22 provided witha stud or roller 23 which travels in a cam groove 24:

in a disk 25 driven atone half the speed of the delivery carrier 6 through the gears 26, 27 The spring 28 serves to yieldingly hold the grippers 8 closed as usual.

From the above description it will be. seen that'the fly is given ample time to perform its functions, Without slowing down the press. tion in connection with means for collecting While I have described the in'ven-.

twosheets from the impressioncylinder it is evident that I do not wish to limit myself, to this particular arrangement but contemplate; the collection of any number of 7 sheets on the delivery carrier to suit varying conditions. What I claim is:

1. An impression cylinder having a pluralityof impression surfaces, a rotary delivery carrier arranged to takesuccessive sheets directly from the impression cylinder surfaces, to collect said sheets, and a fly for taking the so collected sheets directly from the rotary carrier and deliver them.

2. An impression cylinder, a rotary delivery carrier having independently oper- V ated alined sets of grippers arranged to cool lect sheets from the impression cylinder, a fly for delivering the so collected sheets and fmeans for operating one set of grippers every revolution of the carrier and the other set of grippers every second revolution of the carrier. 7 V o An, impression cylinder, a rotary delivery carrier having independently operated alined sets of grippers arranged to colv lect sheets from the impression cylinder and having arms engaging the grippers of one.

a moving the movable cam. '20

deliver the so collected sheets, a rock shaft set andstationary V cams, forengaging the operating arms of the said rock shaft, a :novable cam for engaging the operating arms of the second set ofgrippers and a cam disk driven'from the carrier at half L'An impression cylinder, a rotary delivery carrier having independently operspeed for i twenty-eighth day of October, ,A. D. 191 8.

ated alined sets ofgrippers arranged to collect sheets from the impression cylinder, a

fly for delivering the so collected sheets, means 'for operating one set of grippers every revolution of the carrier and'means for operating the other set of grippers every second revolution of the carrier, the first 'name'd means compr1sing a rock sha-ft hav- .ing arms-engaglng the grippers of one set,

stationary cams for engaging the operating arms of said rock shaft, and the second named means comprising a ovable-cam-for' I engaging the operating arms ofthe gripper shaft and a cam disk driven-frolnthe Gar rier at half speed for moving the movable cam.

In testimonythat I claim the foregoing as my invention, I have signed my name this i HOWARD M. BARBER; Q
